FRED SQUIRE, OF PEABOIDY, KANSAS.

TORGI-L,

Specification of Letters Patent.

Patented Apr. 4, 1922.

Application filed September 11, 1920. Serial No. 409,523.

To all whom it may concern:

Be it known that I, Finn) Somme, a citizen of the United States, residing at Peabody, in the county of Marion and State of Kansas, have invented certain new and useful Improvements in Torches, of which the following is a specification.

My invention relates to improvements in torches and more particularly to the selfgenerating type. D

The primary object of the invention resides in the provision of a device of this character having a relatively large generating chamber affording a maximum heat ing surface for the passage of the fuel 011, thus producing a strong and powerful flow of gas.

A further object lies in providing a devlce of this character adapted and constructed to withstand the intense heat to which it is subjected, being durable, and yet inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate l1ke parts throughout the same,

Figure 1, is a fragmentary side view of my invention; I

Figure 2, is a longitudinally sectional vlew of the same;

Figure 3, is a transverse sectional view on lines 3-3 of Figure 2, and

Figure 1, is an end view.

In the drawings, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the letter A designates generally a generating chamber of tubular configuration having an inlet opening 5 and an outlet opening 6. T he chamber comprises inner and outer walls 7 and 8 arranged in spaced relation to each other, as clearly shown in Figure 2. A spiral partition or wall 9 positioned between the walls 7 and 8 extends the entire length of the generating chamber. This partition divides the casing-so as to provide a spiral passage 10 which encircles the generating chamber as many times as may be desired. The terminal of the passage 10 at the inner end of the chamber, is apertured at 11, from which extends a pipe 12. This pipe extends upwardly at 13, and inwardly as at 14, and has a nozzle 15 attached to its free end which is on a horizontal plane with the center of the chamber. This nozzle is spaced a slight distance from the inlet end 5 of the chamber and is provided with a needle valve 16 which controls and regulates the flow of gas. The opposite end of the passage is likewise apertured through its outer side, as at 17 from which extends the supply pipe 18 positioned along the side of the generating chamber the entire length thereof.

In operation, the fuel oil, preferably kerosene or gasoline, is introduced through the supply pipe being forced through the passage or channel which encircles the generating chamber. The torch is then heated from 125 degrees to 130 degrees Fahrenheit which is sufiicient to vaporize the oil within the chamber converting it into gas which passes through the pipe 12 and is ejected through the nozzle 15. The gas upon being ignited will produce a flame, the force of which is regulated by the needle valve. The flame produced by the gas strikes the inner wall of the generating chamber heating it sufiiciently to vaporize fuel oil passing around the chamber through the passage or channel. Thus it is seen that once the torch is heated it will afterwards generate its own fuel. Particular attention is called to the position of the supply pipe 18 which extends the entire length of the generating chamber, so that the fuel oil is slightly heated before entering the main vaporizing chamber. The spiral passage in the generating chamber which directs the flow of oil provides a maximum heating surface whereby the oil is thoroughly vaporized before being ejected, thus producing a very powerful flame.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus fully described my invention, I claim 1. A torch of the character described comprising cylindrical tube having spaced walls forming a generating chamber, a helical partition between the walls forming a helical channel, a supply pipe communiconnected with the opposite end of said channel, and a jet nozzle covering the outer end of the outlet pipe for regulating the flow of gas.

In testimony whereof, I have aflixed my signature in the presence of two witnesses.

FRED SQUIRE.
